FIELD OF THE INVENTIONThe present disclosure generally relates to medication storage, and, in particular, to secure medication storage.
BACKGROUNDMedications and other regulated products are often required to be stored in secured storage and dispensing mechanisms. Often, an automated dispensing cabinet (ADC) is used to control access to regulated products. ADCs are often expensive and occupy significant space.
In some settings, existing enclosed space such as drawers, cabinets, and carts are used to store and dispense medications. However, some of these enclosed spaces may lack of security and traceability, and those spaces that do have these features may be resource intensive to manage.
Further, to dispense environmentally (e.g., temperature, humidity, light) sensitive items in both acute and non-acute medical settings, refrigerators may be provided. These sensitive items may include delicate, high value medications, and thus it is preferable to monitor and control the refrigerator environment and restrict access to authorized users. While smart refrigerator designs with temperature monitoring and access control may be available, physical access to specialized dispensing terminals or other bespoke hardware is often required, which limits deployment flexibility and increases implementation cost. This can pose a challenge for various care facilities such as doctor's offices, pharmacy clinics, outpatient clinics, institutional infirmaries (e.g., school nurse offices), hospitals, retail clinics, ambulatory clinics, or the like.
Accordingly, there is a need for improved systems and methods of providing refrigerator access control and temperature monitoring, particularly for clinical settings.

The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. Like components are labeled with identical element numbers for ease of understanding. Reference numbers may have letter suffixes appended to indicate separate instances of a common element while being referred to generically by the same number without a suffix letter.
While the following description is directed to the storage of medication using the disclosed access control assemblies, it is to be understood that this description is only an example of usage and does not limit the scope of the claims. Various aspects of the access control assemblies may be used in any application where it is desirable to securely store inventory.
The disclosed access control assembly overcomes several challenges discovered with respect to certain conventional secure medication storage devices. One challenge with certain conventional medication storage devices is that certain conventional medication storage devices may not trace users that accessed stored medication. Further, certain conventional medication storage devices may default to an unlocked state upon depletion of the batteries. Additionally, certain conventional medication devices may be cumbersome and occupy large amounts of space.
In accordance with the present disclosure, it is advantageous to provide access control assemblies as described herein that allow for traceable, space efficient, and secure storage of regulated products, such as medication. The disclosed access control assemblies provide space efficient and secure storage of medication.
Examples of access control assemblies that allow for secure storage are now described.
As illustrated, the cabinet 10 can allow for the storage of inventory within a cabinet volume 16 defined by the cabinet body 12. As can be appreciated, the cabinet volume 16 can securely store items such as medication or other regulated products. In the depicted example, the cabinet volume 16 can be accessed by opening a cabinet door 14. Access to the cabinet volume 16 and items stored therein can be prevented by closing the cabinet door 14. The cabinet door 14 can be movably coupled to the cabinet body 12 by one or more hinges.
As described herein, the cabinet 10 can include an access control assembly 100 to control access into the cabinet volume 16. The access control assembly 100 can lock the cabinet door 14 to the cabinet body 12 to prevent access into the cabinet volume 16 and items stored therein. During operation, the cabinet door 14 can be unlocked or otherwise released upon authentication of a user. The access control assembly 100 can be mounted opposite to the hinges of the cabinet door 14.
In some applications, the access control assembly 100 can be added or retrofitted to existing cabinet doors 14 to add access control to existing cabinets 10. In some applications, cabinets 10 can include the access control assembly 100 upon original manufacture or assembly.
According to various implementations, the access control assembly 100 can include or be embodied as an access control assembly 100 that is utilized or associated with a refrigerator to control access into the refrigerator, as described herein with respect to
In the depicted example, the interface module 110 can control the operation of the latching module 120, allowing a user to gain access to the cabinet volume 16. The interface module 110 can authenticate user inputs and send or display a message, or provide feedback or information, to the user. The interface module 110 can be mounted to an outer surface of the cabinet door 14. In some embodiments, the interface module 110 can be mounted to the cabinet door 14 using existing mounting points for conventional handles.
In the depicted example, the latching module 120 locks and unlocks the cabinet door 14 with the cabinet body 12. As illustrated, the latching module 120 is coupled to an inner surface of the cabinet door 14. In some embodiments, the latching module 120 is mounted opposite to the interface module 110. A mounting bracket 124 can secure the latching module 120 to the cabinet door 14. Optionally, the latching module 120 can be mounted to the cabinet door 14 using the existing mounting points for conventional handles. In some embodiments, the latching module 120 can be secured to the cabinet door 14 by the same fasteners securing the interface module 110.
In an unlocked state, the latching module 120 can allow the cabinet door 14 to be freely opened and closed. The latching module 120 can retract a latching member 122 to prevent the latching member 122 from engaging with the cabinet body 12. The latching member 122 can be moved or actuated by an actuator 126.
In a locked state, the latching module 120 can retain the cabinet door 14 in a closed position. The latching module 120 can extend the latching member 122 to engage against a portion of the cabinet body 12. The latching member 122 can engage against a frame or catch portion of the cabinet body 12. The latching member 122 can be moved or actuated by the actuator 126. As can be appreciated, the actuator 126 can be controlled by the interface module 110.
In the depicted example, the interface module 110 is operatively coupled to the latching module 120. In some embodiments, a connector 109 can provide an interface between the interface module 110 and the latching module 120. A cable can pass through a port 111 formed in the body 112 to engage with the connector 109. In some embodiments, the cable can pass through a hole in the cabinet door 14 to allow direct communication between the interface module 110 and the latching module 120 disposed on opposite sides of the cabinet door 14.
In some embodiments, the interface module 110 can function as an authentication device, can be used to direct and control access to the cabinet 10. In some embodiments, cabinets 10 can be accessed using a personal computer, a tablet computer, a smartphone, a barcode reader, and/or a biometric reader via the interface module 110. During operation, the interface module 110 can provide a plurality of user authentication methods (biometric, smartcard, password, barcode, ECG based wearable device, mobile phone, etc.), allowing the user to select one or more of the authentication methods. The selection may be a user specific configuration, site-specific configuration (e.g., all users at a given site will be authenticated according to the selected method(s)), or system-wide configuration (e.g., all users of the system will be authenticated according to the selected method(s)). The interface module 110 can include a sensing portion 116 to detect user inputs, such as biometrics, near field communication, smartcard, password, barcode, ECG based wearable device, mobile phone, etc. The interface module 110 can utilize any suitable personal area network (PAN) protocols, such as 802.15.4 or Bluetooth Low Energy, or other short-range compatible wireless communication protocol, to communicate with remote devices. In some embodiments, the use of PAN protocols can avoid integration with existing networks, simplifying installation.
Some embodiments provide that remote authentication methods can be implemented to allow a super user to grant remote authorization (e.g., if a user loses their badge or smart phone).
In any embodiment, data generated or detected can be forwarded to a “remote” device or location, where “remote,” means a location or device other than the location or device at which the program is executed. For example, a remote location could be another location (e.g., office, lab, etc.) in the same city, another location in a different city, another location in a different state, another location in a different country, etc. As such, when one item is indicated as being “remote” from another, what is meant is that the two items can be in the same room but separated, or at least in different rooms or different buildings, and can be at least one mile, ten miles, or at least one hundred miles apart. “Communicating” information references transmitting the data representing that information as electrical signals over a suitable communication channel (e.g., a private or public network). “Forwarding” an item refers to any means of getting that item from one location to the next, whether by physically transporting that item or otherwise (where that is possible) and includes, at least in the case of data, physically transporting a medium carrying the data or communicating the data. Examples of communicating media include radio or infra-red transmission channels as well as a network connection to another computing or networked device, and the internet or including email transmissions and information recorded on websites and the like.
The user's authenticated identity can be transmitted to a server to request authorization to access a particular medication or item stored in a respective cabinet 10. Upon receiving authentication, the cabinet 10 can be identified and/or unlocked by retracting the latching member 122 of the latching module 120. In some embodiments, authentication can proceed in an offline mode, allowing the user to proceed without network connectivity. In some embodiments, the authentication device can provide an audible signal (for example from a piezo beeper) to indicate registration of user actions. Optionally, the interface module 110 can trace user access attempts, time of access, date of access, type of medication accessed, etc.
In some embodiments, the interface module 110 can include a position or acceleration sensor to determine if the cabinet door 14 is in an open or closed position. In some embodiments, the interface module 110 can either sense or record the position of the latching member 122 to determine if the latching member 122 is in a locked or unlocked position.
Sensors included in the interface module 110 may include one or more sensors to record, for example, environmental conditions and evidence related to attempts to divert or tamper with the contents of the cabinet. For example, a load sensor may comprise a load cell that can measure the mass of items contained in the cabinet, which can be used to estimate changes in item quantities. A temperature and humidity sensor may record inside and/or outside ambient temperature and humidity. A shock and vibration sensor may help to identify unauthorized access attempts to the cabinet using force. A tamper sensor may determine whether intrusion has occurred or if the cabinet has been removed from a fixture, for example if retaining screws, containers, covers, or other components of cabinet have been opened, unsealed, drilled, deformed, or otherwise tampered. For example, mechanical switches, anti-tamper films, photodiodes with reflective materials, infrared proximity sensors, and other devices may be used. A location sensor may include, for example, a global positioning system (GPS) radio to enable location history tracking. Alternatively or additionally, in some implementations, triangulation may be used to determine location, for example by using Wi-Fi or Bluetooth triangulation using known networks and/or hubs.
In some embodiments, the interface module 110 can include a status indicator 118. The status indicator 118 can display a plurality of colors at various intensities and flash patterns to provide a status of the interface module 110. As can be appreciated, the status indicator 118 can provide different visual indicators based on an identified user and workflow. For example, (i) during a medication loading workflow, the status indicator 118 can provide guidance to the user, (ii) if medication within a cabinet 10 is expired, the status indicator 118 can flash red, (iii) during a medication audit, the status indicator 118 can provide identifying information, and (iv) if the battery level of the interface module 110 is low, the status indicator 118 can provide a low battery signal. In some embodiments, the status indicator 118 includes one or more LED's driven by a FET based drive circuitry. Optionally, the status indicator 118 can be scanned by a handheld device to identify a status (including operating conditions or failure modes) of the storage system. The handheld device can utilize an optical scanner. In some embodiments, the interface module 110 can utilize an audio indicator to provide alerts regarding an open door or drawer.
In some embodiments, the interface module 110 can be powered by disposable or rechargeable batteries 117. As illustrated, the batteries 117 can be inserted into a battery compartment 115 defined at the front of the body 112. A lower cover 114 can cover the battery compartment 115. As can be appreciated, the battery compartment 115 can be accessed from the exterior of the cabinet 10, allowing the batteries 117 to be replaced without unlocking the cabinet 10 or requiring access to the interior of the cabinet 10. In contrast, conventional access control systems may have batteries that are accessed from the interior of a storage area, requiring conventional access control systems to unlock at a low state of charge to facilitate replacement of the batteries. Advantageously, by locating the battery compartment 115 at an exterior accessible location, the cabinet 10 can remain locked when the batteries are at a low state of charge or depleted, permitting the cabinet 10 to remain secured until the batteries 117 are changed.
In some embodiments, the interface module 110 can function as a physical contact point or handle for a user. As illustrated, the body 112 can be formed or shaped to allow a user to grasp the interface module 110 to open or close the cabinet door 14. The body 112 can similarly be shaped to allow a user to open or close a drawer.
In some embodiments, the body 112 can be mounted to an exterior surface of a cabinet door 14 or any other suitable surface. A handle portion 119 of the body 112 can provide a portion of the body 112 for a user to grasp. An extension portion 113 can extend from the handle portion 119 to space the handle portion 119 apart from a mounting surface. As can be appreciated, the extension portion 113 can be narrower to define a recessed area behind the handle portion 119 to allow a user's fingers to grasp the handle portion 119. The extension portion 113 of the body 112 can be coupled or otherwise disposed adjacent to the mounting surface.
In some embodiments, the interface module 110 can communicate with other interface modules 110. For example, the interface module 110 can communicate with each other to share inventory information, etc. In the depicted example, the interface module 110 can wirelessly communicate with other inventory control systems. Optionally, the interface module 110 can include a beacon for asset tracking, environmental sensing, tamper detection monitoring, real time and offline mode support, content identification and/or inventory tracking. The interface module 110 can include tamper resistance features.
In some embodiments, the interface module 110 can utilize one or more power conservation methods. Methods can include placing devices in various low power states to wake up periodically (wake up period), enabling radio communications, checking in with a gateway/hub for updates or to perform transactions. Power saving states can adjust device responsiveness in balance with power savings or low power states. The wake up period can be configured by the gateway/hub for devices based on system usage factors and user preferences. Power states can be adjusted based on user presence, such as if users are present, then devices are placed in more responsive states in anticipation of the system being used. If users are not present the devices are put in less responsive states to maximize power savings.
User presence can be detected in different ways, including users logging into the system or by occupancy sensors such as motion, radar, and proximity sensors. Occupancy sensors can be powered devices located in the storage area and interface to the gateway/hub. In some embodiments, users can input their office schedule into the system and power states can be adjusted based on this schedule. The system can utilize microphones with key word activation. In some embodiments, user actions such as button presses or system usage can wake up the device from deep sleep mode. Power states can be adjusted with machine learning algorithms running locally, on a hub, or on in the cloud.
In some embodiments, the system can harvest energy to increase the operational life of the system. For example, the system can include piezo transducers interfaced to buttons, and/or electromagnetic inductors to harvest energy from the opening or closing of the cabinet doors. Wireless energy can be harvested from RF sources.
As illustrated, the drawer 30 can allow for the storage of inventory within a drawer volume 36 defined by the drawer body 34. As can be appreciated, the drawer volume 36 can securely store items such as medication or other regulated products. In the depicted example, the drawer volume 36 can be accessed by sliding the drawer body 34 away from the drawer frame 32. Access to the drawer volume 36 and items stored therein can be prevented by closing the drawer body 34 within the drawer frame 32. The drawer body 34 can be movably coupled to the drawer frame 32 by one or more slides or rails.
As described herein, the drawer 30 can include an access control assembly 100 to control access into the drawer volume 36. The access control assembly 100 can lock the drawer body 34 to the drawer frame 32 to prevent access into the drawer volume 36 and items stored therein. During operation, the drawer body 34 can be unlocked or otherwise released upon authentication of a user. The access control assembly 100 can be mounted on a front face of the drawer body 34.
In some applications, the access control assembly 100 can be added or retrofitted to existing drawer bodies 34 to add access control to existing drawers 30. In some applications, drawers 30 can include the access control assembly 100.
The subject technology of secure medication storage is described herein. An access control module includes a latching module and an interface module. The latching module includes a latching member and a latch actuator configured to extend and retract the latching member. The interface module is coupled to the latching module. The interface module includes a module body defining a handle portion and an extension portion extending from the handle portion, an input device, and a controller. The controller is operatively coupled to the latch actuator and configured to authenticate the user input and control the latching member in response to the authenticated user input.
Access Control for a Refrigerator
Storage of refrigerated medicines and other healthcare items demand robust access controls and environment monitoring to prevent medicine spoilage, reduce overhead, and minimize costly diversion, theft, and other losses. Various systems may exist to address individual aspects of these demands. However, combining various disparate systems to address the multiple requirements of cold medicine storage may be costly, unwieldy, and difficult or impossible to implement in practice.
The subject technology provides secure access control and environmental monitoring via a smart latch to address the numerous requirements of refrigerated medicine and healthcare item dispensing in care facilities. The smart latch can be attached to existing refrigerators with hinged doors, thereby transforming the refrigerator into a network connected refrigerator with “smart” functionality including environment monitoring and access control. Smart functionality generally refers to processing capabilities and, for the smart latch, environment monitoring and access control processing capabilities. A smart device can have on-board memory or other storage capacity that can be written to and read from. The memory can contain one or more applications for implementing a particular function. The particular smart device may also contain an operating system and/or user interface. Some smart functionality may include wireless communications. For example, a smart device may include a transceiver for communicating through an electric field and/or magnetic field between the device and another entity such as a wireless terminal or information reader.
The smart latch may include various interfaces and devices to support other smart features such as environmental sensing, tamper detection, infrastructure and mesh networking, near-field communications, positional tracking, and user interfaces with audiovisual elements for inventory management, alerts, and user guidance. In this manner, the smart latch can interface and synchronize with a centralized back-end server to support inventory tracking, item condition tracking, and data collection for machine learning, as described in further detail in conjunction with
Smart latch 1130 may include latch opening 1131, which allows latch 1126 to pass through a housing of smart latch 1130 to attach to latch plate 1123, as illustrated in greater detail in conjunction with
Smart latch 1130 may include processor 1134, which may correspond to any type of general or specialized processor, controller, integrated circuit, application specific integrated circuit (ASIC), field programmable gate array (FPGA), system-on-chip, or similar device, and may include hardcoded circuit elements, firmware, software, or any combination thereof to implement one or more of the specific smart latching features describe herein. Processor 1134 may communicate with other components of smart latch 1130 via data bus 1132, which may comprise one or more communication buses, such as parallel or serial buses.
Smart latch 1130 may include memory 1136, which may include volatile work memory as well as non-volatile data store 1137 for long term data storage. For example, non-volatile data storage 1137 may comprise flash memory or other memory that retains data after power source 1180 is unavailable. Non-volatile data store 1137 may include several data logs that record, for example, user authentication events, periodic sensor data, and local inventory of refrigerator 1120.
Communication interface 1140 may include one or more wireless radios to communicate with other devices and/or other smart latches. For example, communication interface 1140 may include one or more radios, scanners, or other devices that are compliant with Bluetooth, Bluetooth Low Energy, Near Field Communication (NFC), Wi-Fi, contactless Smartcards, Radio-Frequency identification, 1-D and 2-D barcodes, and other protocols.
Sensors 1150 may include one or more sensors to record, for example, environmental conditions and evidence related to attempts to divert or tamper with the contents of refrigerator 1120. For example, temperature and humidity sensor 1152 may record outside ambient temperature and humidity. In some implementations, temperature and humidity sensor 1152 may be augmented with inside temperature data received via communication interface 1140, for example from smart containers stored within refrigerator 1120. Shock and vibration sensor 1154 may help to determine whether an attempt to divert has occurred, or whether the contents of refrigerator 1120 were damaged during transport and handling. Tamper sensor 1156 may determine whether case intrusion has occurred, for example if retaining screws, latches, covers, or other components of smart latch 1130 have been opened, unsealed, drilled, deformed, or otherwise tampered. For example, mechanical switches, anti-tamper films, photodiodes with reflective materials, infrared proximity sensors, and other devices may be used. Location sensor 1158 may include, for example, a global positioning system (GPS) radio to enable location history tracking. Alternatively or additionally, in some implementations, triangulation may be used to determine location, for example by using Wi-Fi or Bluetooth triangulation using known networks and/or beacons. In combination with secure crypto-processor 1184, sensors 1150 may securely record real-time sensor data to comply with National Institutes of Standards and Technology (NIST) requirements. Sensors 1150 may include light sensor (not shown). Some items stored within the refrigerator 1120 may be light sensitive. The smart latch 1130 may assess a status of a light sensitive item based on levels recorded by sensors 1150.
Button interface 1160 may enable user input and selections on a user interface. For example, display interface 1164 may show a user interface directing the user to push specific buttons to update inventory, for example. Alternatively or additionally, display interface 1164 may provide a touchscreen panel to accept user input. In some implementations, user input may be received from a remote device, such as a tablet or smartphone, via communication interface 1140.
Light emitting diode (LED) interface 1162 may drive one or more multi-color LEDs or organic LEDs (OLEDs) for providing a quickly identifiable status indication. For example, LEDs may be driven at varied brightness, blinking patterns, and colors to indicate various states of smart latch 1130. In one configuration, solid red LEDs may indicate that sensors 1150 have recorded potentially unsafe environmental conditions for the contents of refrigerator 1120, such as temperature outside of a safety range for medicines, whereas solid green LEDs may indicate that sensors 1150 have recorded environmental conditions within safe parameters. Blinking green LEDs may indicate that an authorized user has submitted valid credentials for unlocking latch 1126 to access the contents of refrigerator 1120. Blinking red LEDs may indicate that tamper sensor 1156 and/or shock and vibration sensor 1154 have recorded an intrusion attempt, for example if a detected deformation, vibration or shock value exceeds a predetermined threshold. Blinking yellow LEDs may indicate that power source 1180 has crossed a low battery threshold and needs replacement. Blinking white LEDs may visually identify refrigerator 1120 to the user, allowing the user to readily identify refrigerator 1120 associated with a requested item in a pharmacy, stock room, or other facility. Further, in some implementations, the LED blinking patterns may be detected by a handheld scanner or another device to assist in inventory tracking and management.
Display interface 1164 may drive a display to show various user interfaces enabling a user to query the inventory of refrigerator 1120, to update the local inventory of refrigerator 1120 by adding or removing items, to query the condition of the items, to display remaining battery life, and to perform other management and status query operations. The user interfaces may utilize text and graphics such as icons, animations, and other elements. In some implementations, these user interfaces may additionally or alternatively be presented on a remote device, such as a tablet or smartphone. Display interface 1164 may drive an electronic ink (e-ink) display, a touchscreen liquid crystal display (LCD), an OLED, or another display type. The information may be presented on the display interface 1164 in human readable form (e.g., letters, numbers, or images) or machine-readable form (e.g., barcode, quick read code, standardized scan code form, or custom scan code form).
Actuator interface 1166 may trigger actuator 1167 to actuate latch 1126, thereby changing lock state 1128 from open to closed and vice versa. For example, latch 1126 may correspond to an electromechanical lock or an electromechanical latch. Actuator interface 1166 may also query latch 1126 to determine lock state 1128. In some implementations, a manual lock may be provided to manually lock and unlock latch 1126 without using actuator interface 1166. In this case, any manual locking or unlocking action may be recorded within an access log in non-volatile data store 1137. A manual lock may be useful to provide access to the contents of refrigerator 1120 when smart latch 1130 malfunctions or when power source 1180 is exhausted and no replacement is readily available.
Identity access management (IAM) interface 1168 may include one or more devices to enable a user to provide credentials for user authentication. For example, IAM interface 1168 may include one or more biometric scanners, such as a fingerprint sensor, an iris scanner, an electrocardiogram (ECG) reader such as a smartwatch, and a depth camera for facial recognition. IAM interface 1168 may also include smartcard readers or other devices to read a contactless smartcard or other unique identifier or token. In some implementations, IAM interface 1168 may use communication interface 1140 to utilize biometric scanners or readers present on a remote device, such as a tablet or smartphone. Accordingly, IAM interface 1168 may receive user credentials which can be validated in conjunction with secure crypto-processor 1184.
When multiple authentication methods are available in IAM interface 1168, then a particular authentication method may be automatically selected for authentication. For example, the authentication methods may be sorted according to security strength, and the methods with the highest security strength may be preferred for use. In some implementations, the user may select the preferred method of authentication. Further, a super user or a user with elevated privileges may manually authenticate a user, for example if the user misplaces his credentials.
Audio interface 1170 may include one or more audio devices, such as microphone 1172 and speaker 1174. Microphone 1172 may enable voice commands to be used instead of button interface 1160 or display interface 1164. Speaker 1174 may enable audio prompts, feedback, and alerts to be emitted. Speaker 1174 may comprise a piezoelectric speaker, a dynamic speaker, or another type of speaker. For example, different tones may be emitted from the piezoelectric speaker to indicate different states or user prompts.
Power source 1180 provides electrical power for the components of smart latch 1130. Power source 1180 may comprise a non-rechargeable battery, a rechargeable battery, a capacitor or super-capacitor, or another energy storage device. Power source 1180 may be user accessible and replaceable. To supplement or recharge power source 1180, power harvester 1182 may be used to receive power from external sources. For example, power harvester 1182 may receive wireless power through inductive coils or RF sources. Power harvester 1182 may also receive power through mechanical action, such as via piezo transducers interfaced to buttons connected to button interface 1160, or via electromagnetic induction induced by actuation movement of latch 1126. Power harvester 1182 may also receive power through direct wired connection, such as via universal serial bus (USB) charging cables, AC-DC chargers, or DC-DC chargers, which may be plugged into an external battery pack or wall mains voltage supply. In the event that power source 1180 is depleted, lock state 1128 may be maintained in its current state, whether closed or open, until power source 1180 is replaced or a manual lock is engaged, when made available.
To extend the operating time of power source 1180, various power management strategies may be utilized. For example, smart latch 1130 may be placed in a low power or sleep state when no activity is anticipated. When activity such as user interactions, periodic network updates, or sensor logging is necessary, smart latch 1130 may wake up to a normal operating mode, and return to the low power or sleep state once the activity is completed. The estimation of low activity may be based on network activity, user preferences, working schedules, or other factors. Smart latch 1130 may also wake up in response to an activation word or phrase via microphone 1172, a button press on button interface 1160, or a touch input from display interface 1164. In some implementations, sensors 1150 may include occupancy sensors which may be used to determine estimated activity levels. In some implementations, microphone 1172 may be used as an occupancy sensor. In some implementations, power management may be based on machine learning algorithms, as described in further detail below in
Secure crypto-processor 1184 may correspond to a trusted platform module (TPM) chip that stores public and private encryption keys for encrypting and decrypting data. For example, the public keys may include public keys of key pairs generated by authorized users, allowing each user to submit credentials encrypted by a respective private key for decrypting by secure crypto-processor 1184. Similarly, private keys specific to smart latch 1130 can be used to encrypt data before transmitting, storing, and exposing the data (e.g., to the outside world). In this manner, data travelling through data bus 1132 and stored in memory 1136, including non-volatile data store 1137, can be securely encrypted to protect against third party eavesdropping and modification. Encrypted data can also be more safely transmitted to the outside world, including over potentially insecure and untrusted networks.
With a block diagram overview of system 1100 now in place, it may be helpful to observe various perspective views of the components of system 1100.
Referring to
In the example shown in
In some implementations, a remote device such as a tablet, smartphone, laptop, or other device may be used to interface with smart latch 1130. For example, the remote device may include an optical scanner that can read 1D or 2D barcodes and/or LED flashing patterns to receive data from smart latch 1130. The scanner may be used, for example, to identify smart latch 1130 for loading medications into refrigerator 1120. For example, smart latch 1130 may include an embedded unique identifier or serial number that can be transmitted using barcodes or LEDs. The remote device may contact a remote server, e.g. a pharmacy server, to determine, for example, a type and quantity of medications to be added refrigerator 1120. Pharmacy and local refrigerator inventories may also be automatically updated according to the expected change in contents of refrigerator 1120. In some implementations, the refrigerator may already be loaded with medications, and the user only needs to identify the correct refrigerator. For example, as discussed above, LED lights may blink on a specific smart latch to identify the refrigerator to the user. A similar process may be used for dispensing medications from refrigerator 1120.
The remote device may execute a local application downloaded from an application store, a corporate network, a website, or another distribution method. Alternatively, the remote device may execute a remote cloud-based application or a Software as a Service (SaaS) application. The application may allow communication with smart latches such as smart latch 1130. For example, the application may utilize radios that support various protocols such as Bluetooth, Bluetooth Low Energy, Near Field Communication (NFC), Wi-Fi, contactless smartcards, Radio-Frequency identification, and others.
When the remote device is connected to a network, such as via a Wi-Fi or cellular connection, smart latch 1130 may utilize the network to communicate and synchronize with a remote server, as described in further detail below in conjunction with
With an overview of the smart latch now in place, it may be helpful to observe the operation of multiple smart latches in an example networked environment.
For example, starting at patient room 1212, a user may utilize a remote device, such as a tablet or smartphone, to request identification of a refrigerator having a requested item. The requested item may be stored in a container, for example smart devices 1290A-1290G that may comprise smart bins or other smart containers. The requested item may also be stored loose within refrigerator 1220A or 1220B.
Server 1214 may use inventory tracking 1215 to track an inventory of each uniquely identifiable smart latch and associated refrigerator. Server 1214 may connect to smart latches 1230A and 1230B via network 1218. Smart latches 1230A and 1230B may connect directly to an infrastructure network of care facility 1210 having access to a public network, such as network 1218, which may comprise the Internet. In some implementations, latches 1230A and 1230B may connect to a private local area network or other network before connecting to network 1218. In some implementations, a cellular router, hub, gateway, modem, or another network device may be provided in each smart latch 1230A and 1230B to provide a connection to network 1218. In this manner, the smart latches can be immediately deployed without requiring potentially costly and time consuming integration into existing information technology (IT) infrastructure at care facility 1210.
As shown in system 1200, each smart latch 1230A and 1230B may communicate with various smart containers and bins stored within each respective refrigerator 1220A and 1220B, for example by providing a wireless repeater network for connecting smart devices 1290A-1290G. Since the smart devices 1290A-1290G may be movable, e.g. moved inside and outside of refrigerators, from one refrigerator to another, and from one room to another, the smart devices 1290A-1290G may potentially lose connection to their initially paired smart latches 1230A and 1230B. In this case, the smart latches and the smart devices may provide mobile mesh network 1219, wherein each smart latch and smart device may function as a mesh node hop to facilitate a connection to network 1218. When a route to server 1214 is not immediately available, then a smart device may operate in an offline mode wherein inventory management is handled locally until a synchronization can occur with server 1214 when a connection route is available.
In some implementations, each smart latch may provide a user interface that accepts requests to identify the location of a particular item, such as medication or medical supplies. Additionally or alternatively, a user may use a remote device, such as a tablet or smartphone, to request identification of a refrigerator storing a particular item. The smart latch containing the item may identify itself to the user by outputting to an audiovisual element, such as by a blinking LED, emitting a sound, or a combination.
For example, the user may use a remote device to request location identification of a refrigerated drug. In some implementations, the remote device may contact a centralized service, such as server 1214, which in turn may query inventory tracking 1215 to find a refrigerator containing the drug that is closest to the user. To determine the smart latch/refrigerator that is closest the user, the position of the remote device and refrigerator may be detected using GPS and/or triangulated based on the availability of known network connections to the remote device and the smart latch/refrigerator.
In some implementations, the remote device may utilize mobile mesh network 1219 to find the closest smart latch/refrigerator containing the requested refrigerated drug. For example, each smart latch may query the inventory of the smart devices in the associated refrigerator to determine a local inventory. Further, each node in mobile mesh network 1219 may broadcast and propagate their own position and inventory to all other nodes, allowing a local cache of node locations and inventory to be stored by each node. In this manner, each node can quickly determine, from the local cache, the closest node where the requested refrigerated drug is possibly present. Since the local cache may be potentially out of date, a node may verify whether the refrigerated drug is actually still present by using mobile mesh network 1219 to send a query to the closest node. Once the closest node is determined, then a location of the closest node may be displayed on a map, e.g. on display 1165 or on a display of a remote device. If the refrigerated drug is not present, then the node may respond by providing the last authorized user and access time.
In this manner, devices connected to mobile mesh network 1219 may cooperatively determine that the requested drug is contained within smart device 1290B within refrigerator 1220A. Alternatively, server 1214 may utilize inventory tracking 1215 to make the same determination. As a result, server 1214 may instruct smart latch 1230A to enter into an alert or identification mode, wherein a LED flashes white to guide the user to refrigerator 1220A. The remote device may also display a map to guide the user to refrigerator 1220A. Further, any smart devices between the user and the destination, or refrigerator 1220A, may be directed to illuminate a path. For example, if the request is initiated at or near smart latch 1230B, then smart devices 1290C and 1290D may be illuminated to show a path to smart latch 1230A and refrigerator 1220A.
In some implementations, the alert emitted by smart latch 1230A may change depending on the user's proximity to refrigerator 1220A. For example, a LED on smart latch 1230A may flash when the user is within a proximity threshold, whereas a piezoelectric speaker on smart latch 1230A may beep when the user is outside of the proximity threshold. Once the door to refrigerator 1220A is opened, the specific container with the requested drug may also alert the user. For example, smart device 1290B may be directed to emit similar LED flashing alerts.
As shown in server 1214, inventory tracking 1215, item condition tracking 1216, and machine learning 1217 may be updated according to status information provided by each smart latch. For example, inventory tracking 1215, item condition tracking 1216, and machine learning 1217 may track the location, quantity, and condition of various medicines and healthcare items inside refrigerators 1220A and 1220B. Inventory tracking 1215 may be updated to reflect items added or removed from smart devices 1290A-1290G, for example by using the repeater networks provided by smart latches 1230A-1230B to query the inventory of the smart devices 1290A-1290G. Item condition tracking 1216 may be updated according to changing environmental conditions experienced by each smart device and smart latch. Machine learning 1217 may record device interactions and usage data for each smart latch 1230A-1230B. Referring to
At least a portion of the smart latch usage data may be processed by one or more machine learning algorithms to determine a power management profile that can be pushed back to smart latches 1230A-1230B for optimized power consumption. For example, the power management profile may define daily time periods when user interactions are infrequent. Smart latches 1230A-1230B may use this profile to transition the processor and other components to a low power idle or sleep mode during these daily time periods.
Each smart latch may also support real-time status reporting when a network connection route is available. For example, a client may query server 1214 for the status of a specific smart latch. Assuming that server 1214 can establish a network route to communicate with the requested smart latch, the smart latch may be queried for the requested status, such as environmental condition, tamper attempt history, or refrigerator inventory status, and the smart latch may respond by sending an encrypted message containing the requested status. Global searches may also be supported to query the status of multiple smart latches within a network. For example, one global search may request a list of refrigerators reporting internal temperatures above a threshold range, or a list of refrigerators sorted by internal temperatures.
Since the smart latches 1230A and 1230B have a built in display 1165 as shown in
Display 1365A shows a general purpose status screen, which may be shown by default when no user interaction is taking place. As shown in display 1365A, the status screen may include several informational fields, such as a description of contents and temperature, a battery level, a network status, and door open status. Referring to
Once a user submits user credentials that are verified and authorized, the smart latch may open and the user may open the door, as indicated in display 1365B. In some implementations, a mechanical opener, spring, or other device may be used to automatically open and close the door.
The internal temperature of the refrigerator may begin to exceed safe temperature ranges, for example when a compressor failure occurs or the door is not securely shut. In this case, a warning message may be shown, as shown in display 1365C. The warnings may also be logged into a non-volatile data store, along with authentication and access logs that can identify the user who authorized refrigerator access at the time. Other alerts such as audible alarms or flashing LEDs may also be used to bring attention to the temperature warning.
In the depicted example flow diagram, a smart latch is provided for attaching to a refrigerator (1411). Referring to
Process 1400 may continue with retrieving, via a communication interface, inventory and temperature status for one or more smart containers within the refrigerator (1412). Referring to
Processor 1134 may continue to output, via a display, the inventory and temperature status (1413). For example, referring to
Processor 1134 may continue receiving a user credential for accessing the refrigerator (1414). For example, referring to
Processor 1134 may continue to validate the user credential for accessing the refrigerator (1415). For example, referring to
Processor 1134 may continue to trigger an actuator to open a lock, thereby allowing a door of the refrigerator to be opened (1416). For example, referring to
Processor 1134 may continue to trigger the actuator to close the latch after detecting that the door is closed, thereby securing the door (1417). For example, the user may manually close the door. In some implementations, the spring, mechanical opener, or other assistive device used to open the door (1416) may also be used to close the door, for example by triggering a closing of the door after a temperature change exceeds a threshold range, which may depend on the safe temperature range of items contained in the refrigerator. Referring to
In some implementations, processor 1134 may continue to synchronize the local inventory with a remote server via a communication interface. For example, referring to
In this manner, inventory tracking 1215 can be automatically updated with the current location and inventory for each refrigerator equipped with a smart latch, enabling detailed insight for medical supply restocking, loss prevention, and other management tasks. Similarly, item condition tracking 1216 may be updated to track environmental conditions (e.g. whether safe temperature ranges are maintained) and item quality, and machine learning 1217 may be updated with smart latch usage statistics to provide training data for power management profile generation.
Many aspects of the above-described example process 1400, and related features and applications, may also be implemented as software processes that are specified as a set of instructions recorded on a computer readable storage medium (also referred to as computer readable medium), and may be executed automatically (e.g., without user intervention). When these instructions are executed by one or more processing unit(s) (e.g., one or more processors, cores of processors, or other processing units), they cause the processing unit(s) to perform the actions indicated in the instructions. Examples of computer readable media include, but are not limited to, CD-ROMs, flash drives, RAM chips, hard drives, EPROMs, etc. The computer readable media does not include carrier waves and electronic signals passing wirelessly or over wired connections.
The term “software” is meant to include, where appropriate, firmware residing in read-only memory or applications stored in magnetic storage, which can be read into memory for processing by a processor. Also, in some implementations, multiple software aspects of the subject disclosure can be implemented as sub-parts of a larger program while remaining distinct software aspects of the subject disclosure. In some implementations, multiple software aspects can also be implemented as separate programs. Finally, any combination of separate programs that together implement a software aspect described here is within the scope of the subject disclosure. In some implementations, the software programs, when installed to operate on one or more electronic systems, define one or more specific machine implementations that execute and perform the operations of the software programs.
A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.
Electronic system 1500 may include various types of computer readable media and interfaces for various other types of computer readable media. In the depicted example, electronic system 1500 includes a bus 1508, processing unit(s) 1512, a system memory 1504, a read-only memory (ROM) 1510, a permanent storage device 1502, an input device interface 1514, an output device interface 1506, and one or more network interfaces 1516. In some implementations, electronic system 1500 may include or be integrated with other computing devices or circuitry for operation of the various components and processes previously described.
Bus 1508 collectively represents all system, peripheral, and chipset buses that communicatively connect the numerous internal devices of electronic system 1500. For instance, bus 1508 communicatively connects processing unit(s) 1512 with ROM 1510, system memory 1504, and permanent storage device 1502.
From these various memory units, processing unit(s) 1512 retrieves instructions to execute and data to process in order to execute the processes of the subject disclosure. The processing unit(s) can be a single processor or a multi-core processor in different implementations.
ROM 1510 stores static data and instructions that are needed by processing unit(s) 1512 and other modules of the electronic system. Permanent storage device 1502, on the other hand, is a read-and-write memory device. This device is a non-volatile memory unit that stores instructions and data even when electronic system 1500 is off. Some implementations of the subject disclosure use a mass-storage device (such as a magnetic or optical disk and its corresponding disk drive) as permanent storage device 1502.
Some implementations use a removable storage device (such as a floppy disk, flash drive, and its corresponding disk drive) as permanent storage device 1502. Like permanent storage device 1502, system memory 1504 is a read-and-write memory device. However, unlike storage device 1502, system memory 1504 is a volatile read-and-write memory, such a random access memory. System memory 1504 stores some of the instructions and data that the processor needs at runtime. In some implementations, the processes of the subject disclosure are stored in system memory 1504, permanent storage device 1502, and/or ROM 1510. From these various memory units, processing unit(s) 1512 retrieves instructions to execute and data to process in order to execute the processes of some implementations.
Bus 1508 also connects to input and output device interfaces 1514 and 1506. Input device interface 1514 enables the user to communicate information and select commands to the electronic system. Input devices used with input device interface 1514 include, e.g., alphanumeric keyboards and pointing devices (also called “cursor control devices”). Output device interfaces 1506 enables, e.g., the display of images generated by the electronic system 1500. Output devices used with output device interface 1506 include, e.g., printers and display devices, such as cathode ray tubes (CRT) or liquid crystal displays (LCD). Some implementations include devices such as a touchscreen that functions as both input and output devices.
Also, bus 1508 also couples electronic system 1500 to a network (not shown) through network interfaces 1516. Network interfaces 1516 may include, e.g., a wireless access point (e.g., Bluetooth or WiFi) or radio circuitry for connecting to a wireless access point. Network interfaces 1516 may also include hardware (e.g., Ethernet hardware) for connecting the computer to a part of a network of computers such as a local area network (“LAN”), a wide area network (“WAN”), wireless LAN, or an Intranet, or a network of networks, such as the Internet. Any or all components of electronic system 1500 can be used in conjunction with the subject disclosure.
The subject technology provides secure access control and temperature monitoring of medicine and healthcare items stored within refrigerators in clinical settings. A method includes providing a smart latch for attaching to the refrigerator. The method also includes retrieving, via a communication interface, inventory and temperature status for one or more smart containers within the refrigerator. The method also includes outputting, via a display, the inventory and temperature status. The method also includes receiving a user credential for accessing the refrigerator. The method also includes validating the user credential for accessing the refrigerator. The method also includes triggering an actuator to open a latch, thereby allowing a door of the refrigerator to be opened. The method also includes triggering the actuator to close the latch after detecting that the door is closed, thereby securing the door.
Cabinet Smart Lock
One aspect of the disclosure relates to a system, device, and/or method that includes an enhanced lock for cabinet doors or drawers (“cabinet smart lock” or “smart lock”). The described smart lock system, devices, and corresponding methods facilitate securing medication inside cabinets and drawers in both acute and non-acute healthcare settings. The smart lock may be a wirelessly connected device with a locking mechanism to secure the medication, authentication capabilities to provide secure access and a user interfaces. The smart lock is configurable and users may be able to authenticate directly at the smart lock, or can use other methods such as logging onto a tablet or using a standalone authentication module to access the system or component connected thereto (e.g, a cabinet smart lock). According to various implementations, one or more user interfaces may include multi-color light emitting diodes (LEDs) and E-Ink display which are also configurable. Some implementations may include a machine learning (ML) inference and data analytics engine to dynamically adjust a power state of the smart lock to optimize power consumption on a smart lock device and/or system based on analysis of a lock's usage context. Some implementations may include a handheld device or mobile application that can scan multicolor LED and identify system status during manufacturing or field.
Existing solutions in non-acute space for securing medications involve off the shelf keyed or combination locks that are installed on the cabinets and drawers. Users use the same key or combination numbers to access medication, which is not traceable as to who accessed the cabinets. Wireless lock technologies that connect directly to a phone or mobile device are generally for personal use, but do not integrate into an enterprise level solution. The systems and method described herein includes an enterprise level solution that provides traceability and is integrated with medication workflows. The described systems and methods address these and other shortcomings of the existing lock technologies.
Disclosed is a smart lock system, device, and methods used to secure cabinets and drawers in non-acute and acute healthcare settings:
The E-ink user interface of the device may, in some implementations, display status of the smart lock system using icons such as battery level, network connectivity, status of the latch and door.
The E-ink user interface of the device may, in some implementations, in some implementations may display alerts such as expired medication, medication below par, tamper detection and etc.
The E-ink user interface of the device may, in some implementations, display information collected from the environmental sensor. Examples of such information collected include temperature of medication, monitor tamper evidence sensor signal, humidity, shock, and vibration over time.
The E-ink user interface of the device may, in some implementations, dynamically display information based on configuration associated with the user as to the contents of the display.
In some implementations, the multicolor LED user interface may act as a glanceable status indicator. The LED color, flash pattern, or intensity may be adjusted by the device (or in response to a control signal from a central control server) to indicate different status. The status may be based on user accessing the secure storage location, workflow, inventory level, or other detectable characteristic of the device or contents thereof.
Example 1: During medication loading workflow the LED lighting can guide the user to the medication at a glance.
Example 2: If the medications being secured by the smart lock has expired the LED can flash red.
Example 3: During medication audit the system may guide by lighting the LED's so the user can identify the med easily.
Example 4: If the battery level lower than threshold LED can flash in low intensity.
Example 5: LED color and flash pattern to indicate authorized user unlocked the latch.
Also provided is a computer implemented method by which a handheld device can scan the LED color, intensity and flash pattern and identify its status during manufacturing or in field. The computer-implemented method may be performed under control of one or more processing devices (e.g., CPUs or computer systems and/or devices).
The method may be implemented, in whole or in part, using an inspection equipment, a mobile application, and an optical reading device to read the multicolor visual indicator and analyze the reading to determine the failure modes and conditions on smart lock. Reading the indicator may include capturing an image of the LED. Reading the indicator may include capturing a series of images of the LED. The series may be captured for a period of time or number of frames identified using a configuration value. The series may be captured based on information encoded by the LEDs. For example, a preamble pattern or color may identify the start or end of a status sequence. When the device reads this pattern for a second time, the device may terminate reading and being the analysis of the captured image(s).
The authentication system may automatically determine a plurality of user authorization methods. The user may select one of the determined authorization methods to unlock the smart lock.
Features are also described for securely transmitting a user identity to a server and transmitting an authorization to unlock the smart lock. The authentication may, in some implementations, include reading data from a contactless smart card. In other implementations, it may use barcode, biometric identification, ECG based wearable device, a mobile phone, or a combination of the authorizations to request unlocking of a smart lock.
The authentication may include remote authentication. For example, users can enter credentials at tablet or PC or use a standalone authentication module to gain access to the smart lock or if the user loses their badge or smart phone a super user can provide remote authentication.
The sensor interface in an environment associated with a smart lock may monitor NIST traceable environmental sensor or tamper detection data in real time (e.g., within a threshold period of time from actual occurrence of the sensed environment condition or tamper event).
The systems or methods may generate an audible sound acknowledging user actions such as presenting badge to the smart lock or when an actuator command is been executed.
For example, in some implementation, a piezo beeper may be configured to emit different tones whereby each tone indicates a different action.
The communication architecture (CA) for the systems and methods, may include one or more of a plurality of personal area network (PAN) protocols such as (802.15.4/BLE) to communicate with the remote device.
The CA may be configured to detect beacon signals for asset tracking, provide environmental sensor and tamper detection monitoring, generate real time and offline mode support, or identify tote contents and track inventory. Because some health care supplies are temperature sensitive, if an environmental sensor determines that the temperature or humidity to which an item was exposed is outside an expected range, the system may dynamically adjust to alert or prevent dispensing of exposed items. Similarly, a sensitive item may have been tampered with. The system may direct storage or prevent distribution of such items until the integrity is confirmed. The confirmation may include an authorized user verifying the item before being eligible for dispensing and use in the healthcare facility.
According to various implementations, the smart lock CA can bypass set up and attachment to hospital IT resources. This can reduce implementation time and make it a drop ship model because of PAN protocol support.
A smart lock device may be configured to act as a companion device for devices placed inside the enclosure to bridge communications. Connected devices placed inside enclosures, such as refrigerators and metal cabinets, may have their radio signals attenuated and have difficulty communicating to hubs located further away. In these cases, another device such as the Smart lock is used as companion device to enable reliable communication to the hub/gateway. Smart lock when acting as a companion device can fill two roles: (i) a slave role communicating to the hub; (ii) a master role communicating to the devices behind the enclosure.
The power architecture of the smart lock device and/or system may include disposable batteries and in other implementations it may include rechargeable batteries. To improve efficiency of the devices by conserving power in battery operated devices, the power management module may operate based on system factors and user preference. The power management module may be implemented within a specific device to conserve resources of the device in which it is implemented. The power management module may be a central device configured to manage power for a group of devices in data communication therewith.
Devices may be placed in various low power states and may be configured to wake up periodically. The power management module may transmit a control signal to the devices in various low power states to wake up them up periodically (wake up period) and enable radio communications and check in with a gateway/hub for updates or to perform transactions.
The power saving states may be used to adjust device responsiveness versus power savings. The low power states and wake up period may be dynamically configured by the gateway/hub for devices based on system usage factors and user preferences.
Power states may be adjusted based on user presence. For example, if a sensor detects that users are present, the devices may be controlled to operate in more responsive states in anticipation of the system being used. If a sensor detects that users are not present or have left an area including one or more devices, the power management module may adjust devices within the area to operate in less responsive states, to maximize power savings.
User presence can detected in different ways including users logging into the system or by occupancy sensors such as motion, radar, and proximity sensors. Occupancy sensors are envisaged to be powered devices located in the health care service area (e.g., examination room, procedure room) and interface to the gateway/hub.
In some instances, users may provide an office schedule into the system and power states are adjusted based on this schedule (e.g., when an appointment is included for a time period on the schedule). The office schedule may indicate times when clinicians are working in the health care facility. Similar power adjustments may be controlled based on shifts when clinicians are active as indicated by the schedule.
Some instances may include microphones coupled with a speech detection system. The speech detection system may identify a key word to activate one or more device (e.g., adjust power state to an active/ready mode).

For example, a remote location could be another location (e.g., office, lab, etc.) in the same city, another location in a different city, another location in a different state, another location in a different country, etc. As such, when one item is indicated as being “remote” from another, what is meant is that the two items can be in the same room but separated, or at least in different rooms or different buildings, and can be at least one mile, ten miles, or at least one hundred miles apart. “Communicating” information references transmitting the data representing that information as electrical signals over a suitable communication channel (e.g., a private or public network). “Forwarding” an item refers to any means of getting that item from one location to the next, whether by physically transporting that item or otherwise (where that is possible) and includes, at least in the case of data, physically transporting a medium carrying the data or communicating the data. Examples of communicating media include radio or infra-red transmission channels as well as a network connection to another computer or networked device, and the internet or including email transmissions and information recorded on websites and the like.
In one aspect, unless otherwise stated, all measurements, values, ratings, positions, magnitudes, sizes, and other specifications that are set forth in this specification, including in the claims that follow, are approximate, not exact. In one aspect, they are intended to have a reasonable range that is consistent with the functions to which they relate and with what is customary in the art to which they pertain.
Features described may include machine learning. Machine learning may include models, equations, artificial neural networks, recurrent neural networks, convolutional neural networks, decision trees, or other machine readable artificial intelligence structure. Examples of machine learning and modeling features which may be included in the embodiments discussed above are described in “A survey of machine learning for big data processing” by Qiu et al. in EURASIP Journal on Advances in Signal Processing (2016) which is hereby incorporated by reference in its entirety.
In one aspect, the term “coupled” or the like may refer to being directly coupled. In another aspect, the term “coupled” or the like may refer to being indirectly coupled.
Terms such as “top,” “bottom,” “front,” “rear” and the like if used in this disclosure should be understood as referring to an arbitrary frame of reference, rather than to the ordinary gravitational frame of reference. Thus, a top surface, a bottom surface, a front surface, and a rear surface may extend upwardly, downwardly, diagonally, or horizontally in a gravitational frame of reference.
Various items may be arranged differently (e.g., arranged in a different order, or partitioned in a different way) all without departing from the scope of the subject technology. All structural and functional equivalents to the elements of the various aspects described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. No claim element is to be construed under the provisions of 35 U.S.C. § 112, sixth paragraph, unless the element is expressly recited using the phrase “means for” or, in the case of a method claim, the element is recited using the phrase “step for.” Furthermore, to the extent that the term “include,” “have,” or the like is used, such term is intended to be inclusive in a manner similar to the term “comprise” as “comprise” is interpreted when employed as a transitional word in a claim.
The Title, Background, Summary, Brief Description of the Drawings and Abstract of the disclosure are hereby incorporated into the disclosure and are provided as illustrative examples of the disclosure, not as restrictive descriptions. It is submitted with the understanding that they will not be used to limit the scope or meaning of the claims. In addition, in the Detailed Description, it can be seen that the description provides illustrative examples and the various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed configuration or operation. The following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter.
The claims are not intended to be limited to the aspects described herein, but is to be accorded the full scope consistent with the language claims and to encompass all legal equivalents. Notwithstanding, none of the claims are intended to embrace subject matter that fails to satisfy the requirement of 35 U.S.C. § 101, 102, or 103, nor should they be interpreted in such a way.
Claims
1. A smart latch attachable to an enclosure of a refrigerator, the smart latch comprising:
- an actuator configured to open and close a latch to secure a door of the enclosure;
- a communication interface;
- a non-transitory machine-readable memory,
- a display; and
